But Dan soon finds that there are limits to his powers and forces beyond his control.

A rebel force unites with other worlds to keep genetically-engineered predators from enslaving the galaxy. Nominated four times for the Nebula Award and author of the gripping War Against the Chtorr series, David Gerrold has created a spectacular new science fiction adventure set in the far future.

"Still reeling from the alien plagues that killed two-thirds of the planet's population, humanity now confronts the most deadly enemy Earth has ever known... the giant, man-eating Chtorr. Lieutenant James McCarthy has grown to manhood under the shadow of the terrifying invasion of the Chtorr. As a student, he learned all he could to understand their alien behavior. As a Special Forces commando, he made violent first contact. Now this battle-hardened warrior faces a profound challenge. Captured by an anarchistic band of men and women known as renegades, McCarthy must secretly gather vital information while fighting indoctrination into their cult... which serves and worships the Chtorr."--Back cover.

A young woman is brought aboard the "U.S.S. Enterprise" by Lt. Reilly's contact team, unaware that any world exists outside her own spaceship. With her craft plagued by mutiny, Kirk and company must gain control of the ship before it, and their disoriented passenger's identity, are destroyed. They also need to convince the woman that their purpose is not part of a malefic scheme, as she fears. The crew also realizes that it would be better to sway her feelings before she gets a good look at Spock!

"Hella is a planet where everything is oversized--especially the ambitions of the colonists. The trees are mile-high, the dinosaur herds are huge, and the weather is extreme--so extreme, the colonists have to migrate twice a year to escape the blistering heat of summer and the atmosphere-freezing cold of winter. Kyle is a neuro-atypical young man, emotionally challenged, but with an implant that gives him real-time access to the colony's computer network, making him a very misunderstood savant. When an overburdened starship arrives, he becomes the link between the established colonists and the refugees from a ravaged Earth. The Hella colony is barely self-sufficient. Can it stand the strain of a thousand new arrivals, bringing with them the same kinds of problems they thought they were fleeing? Despite the dangers to himself and his family, Kyle is in the middle of everything--in possession of the most dangerous secret of all. Will he be caught in a growing political conspiracy? Will his reawakened emotions overwhelm his rationality? Or will he be able to use his unique ability to prevent disaster?"--Provided by publisher.

McCarthy was drafted from his college biology studies and became a member of the Special Forces. Then he is given the opportunity to contact the Chtorr, but when a helicopter crash leaves him and his companions stranded in enemy territory, he must decide whether to communicate with the Chtorr--or kill them!

Having barely escaped death at the hands of ruthless corporations who have pursued him across the harsh lunar wasteland, teenager Charles Dingillian faces yet another fateful decision: no longer able to return to his home on Earth, Charles and his two brothers must choose a new planet to call home. But which one? Charles has come into possession of a prototype HARLIE unit so revolutionary and state-of-the-art that corporations will stop at nothing - including murder - to control it. Earth is in a state of social and economic meltdown. The battle for domination between rival corporations has gone interplanetary. Charles and the HARLIE unit escape capture on Earth, but the hunt for them intensifies when they are discovered to be on the moon. The stakes have escalated to full-scale war. For Charles, everyone is his enemy. No one can be trusted. Charles has been at war before: only that was a personal civil war waged between him and his parents. In an effort to end the strife once and for all thirteen-year-old Charles took the drastic step of "divorcing" his parents. When against all odds he succeeded, he won his freedom. He and his brothers are now free to do what they choose. To go where they want. Freedom for Charles and his brothers means passage on a starship to a colony Outbeyond. There they will use HARLIE to help build a better world. But freedom also means exile. From his home. From his friends. From everything he has ever known. And even his chance for a new life on a remote planet is put in jeopardy when a critical malfunction with the HARLIE unit seemingly threatens the integrity of the voyage. However, a faction of passengers on board the Brightliner Cascade may pose an even greater risk. A risk not even an intelligence as powerful as a HARLIE unit can avert.

Everyday themes as diverse as exploration, the fight against evil, laboratory experiments, and self-improvement are presented in this new anthology of short stories from David Gerrold. Largely consisting of stories featuring an alternative history, and often written for Mike Resnick's Alternative series, the stories range from funny to horrifying and lighthearted to profound. In "Franz Kafka, Superhero!" Kafka employs his unusual metamorphosis to fight evil throughout the world and take on even Sigmund Freud. Two characters who hope to better themselves experience "The Seminar from Hell," while "The Firebringers" features Humphrey Bogart, Gregory Peck, Ronald Reagan, and Jimmy Stewart as soldiers charged with dropping the first atom bomb. Taking an archaeological turn, a team of anthropologists struggles with understanding the artifacts of a mysterious alien race in "Digging in Gehenna." With wit and imagination, these pieces provide a rare and intriguing addition to any Gerrold collection.

On a small, insignificant planet called Thoska-Roole, a ragtag alliance of humans, androids, and bioforms make a last desperate stand against Phaestor domination. Among their numbers are two bounty hunters, a mercenary starship captain, and a disgraced reptilians warrior. As the Phaestor begin a new reign of unprecendented terror, these rebels prepare to strike back against their vampire overlords and bring revolution to the stars.
